hi, i want to share a problem of a friend.
his computer got locked( you can do nothing but restart computer) everytime after he begins to use it like after 10 minutes. he thought maybe the problem was in system and erased it but when he tried to load it(windows xp) again it got locked again.
about locking(sorry for english): the image on screen freezes, keyboard or mouse doesnt respond.Sounds like it could be a heat problem.
Check the fans inside the case and gently clean them with a slightly damp cloth, wipe them free of dust.
Be careful not to damage anything whilst you're in the case and observe ESD precautions.
See if that helps.
ALSO, start the PC up with the case open and check all the fans are spinning.
Post back with a report on how the PC is after you've cleaned the fans and whether all the fans are spinning.
Also, what are the details on that PC?we checked the fans, they are clean and working. it seems it isnt heat problem. here are some details of pc: a-open motherboard, pen.4 2 mhz proc., 640rd ram, ASUS g-force 256 mb graphic card.
thanks for help anywayIt must be a hardware problem, IF he reformatted and REINSTALLED Windows correctly.
If it was me, I'd REFORMAT the hard drive and start from scratch again.
Sounds like he hasn't got much to LOSE from this installation anyway if he's already reloaded it and it's messed up.he can not reinstall windows correctly because pc get crazy everytime after he opens it(after 10 minutes or so)So the problem even happens when Windows isn't even running?
It's definitely a hardware problem of some sort if that is the case.yes, we think also it's a hardware problem, but which part? anyway, thank for your interest!  Power Supply

Bad RAM

Blown capicitor on the MBoard...

Not neccessarily in that order.
